Reacting monomers in a chain reaction is called?

• A. Condensation
• B. Polymerization
• C. Cross-linking
• D. Isomerization

Answer: (B)

Polymerization is the process where monomers join together to form a larger molecule, a polymer. When monomers react in a chain-growth fashion, each step adds another monomer to the growing chain, creating long, repeating units. This sequence—initiation to generate reactive centers, propagation to keep adding monomers, and termination to finish the chain—defines polymerization. Other terms describe different ideas: condensation refers to polymer formation with loss of a small byproduct, cross-linking links separate chains into a network, and isomerization is just rearranging atoms within a molecule without building a longer chain.
